Abstract
This paper deals with the dynamic stability of long-span bridges under non-stationary aerodynamic loads. Some generalizations of classical models are presented in order to check the critical conditions both in the case of flutter and divergence for long-span bridges with particular reference to the cable-stayed scheme. Furthermore, a numerical model based on a finite volume formulation of the flow problem around the girder cross-section is developed, able to simulate the steady and non-steady wind load conditions on the bridge. Good agreement with wind tunnel test results is found for the Normandy Bridge design cross-section models.
